Which is the correct simplification of 2.2*10^4/8.8*10^9 written in scientific notation ?

a) 0.25*10^5
b) 2.5*10^6
c) 0.25*10^-5
d) 2.5*10^-6

I think it is either a or c, but please help.

* means multiplication sign

Thank You !

What makes you "think" it is either a or c

What did you do to get the answer?

You are only cheatinv yourself and not learning a lick. If you payed attention to the lesson and did the extra work would know how to work this problem. We just had a quiz dropped because you guys are cheating on here. I am letting the principles know. We all lose out when you do this. Go to the live lessons!

So what was the answer

To find the correct simplification of 2.2*10^4/8.8*10^9 in scientific notation, you can follow these steps:

Step 1: Simplify the numerator and denominator separately:
2.2*10^4 = 22,000 (since 10^4 means 10,000)
8.8*10^9 = 8,800,000,000 (since 10^9 means 1,000,000,000)

Step 2: Divide the numerator by the denominator:
22,000 ÷ 8,800,000,000 = 0.0000025 (or 2.5 × 10^-6 in scientific notation)

Therefore, the correct simplification in scientific notation is d) 2.5*10^-6.

Hope this helps!
